RAKE

Specification of Letters Patent.

Patented May 5, 1908.

- Application filed February 18, 1907. Serial No. 358,043.

To all whom it may concern:

Be it known that I, BENJAMIN H. ELLIs, a citizen of the United States ofAmerica, residing at Detroit, in the county of Vayne and State ofMichigan, have invented certain new and useful Improvements in Rakes, ofwhich the following is a specification, reference being had therein tothe accompanying drawmgs.

The invention relates to a rake of the char acter wherein means areprovided for conveying the collected material from the rake teeth toasuitable receptacle in which the material may be deposited, and itconsists in the novel and simple construction of rake, and in thepeculiar arrangement and combination of its parts.

In the drawings,-Figure 1 is a front elevation of a rake embodying myinvention; Fig. 2 is a vertical longitudinal section therethrough; Fig.3 is a plan view, illustrating a yielding connection between the carrierblades and their support; and Fig. 4 is a section taken on lines l1 ofFig. 3. Fig. 5 is a detached perspective view, illustrating theconstruction and arrangement of the toothcarrying bar and. bridgingmember.

In construction, the rake is composed of a main or body section, A,consisting of suitable sides B and a bottom plate 0.

D are supporting wheels for the body at its lower end, secured upon atransverse shaft D journaled in the body sides, and E is a supportingframe carrying a transverse roller E depending from the upper rearportion of the body, and adapted to hold the latter in an upwardlyinclined position, as indicated in Fig. 2.

F represents a series of rake teeth attached to a transverse bar G,mounted in guides H upon the lower portion of the body for longi tudinalsliding movement, and I is a plate adapted to be secured either to thebody or the sliding bar G, and in this instance is shown as attached tothe latter bar, the plate extending upwardly to and over the bottomplate, forming a bridging member to cover the space between the parts.To prevent the teeth from digging into the ground during the operationof the rake, the ends are return-bent, as shown in Fig. 2, therearwardly-eXtending portions J being preferably parallel with andcontacting with the ground in the normal position of the parts.

For conveying the material away from the rake teeth, a carrier K isprovided, consisting of chains,preferably of the sprocket type, L,sprocket wheels L fixedly secured to the shaft D, and similar sprocketwheels L upon a transverse shaft L journaled in the upper end portionsof the body sides, as shown Fig. 2. The carrier is provided withtransverse blades M, preferably angle-shaped in form, and so arrangedand apportioned as to bear against the bottom section during theirupward movement to convey the material along the bottom and dischargethe same over its upper edge into a suitable receptacle M secured to thebody.

To prevent breakage of parts, in the event that stones or similararticles are picked up by the rake, I form a yielding connection betweeneach of the carrier blades and the supporting chain, which permits theblade when encountering the obstacle to yield sufficiently to pass overit. The yielding connection is preferably in the form of a springbacking, ,as shown in Figs. 3 and 4, formed of spaced-ears a struck upfrom the end portions of each carrier blade, and boxes of U-shapedconstruction I), secured in any suitable manner to a lug 0 carried bythe chain, a bolt (1 extending through the boX and the blade ears, and aspring e encircling the pivot bolt, its ends arranged to bearrespectively against the blade and the boX, thus forming the yieldingabutment referred to.

O represents a suitable handle section for the rake to permit of itsoperation, consisting in this instance of side bars P and Q fixedlysecured to the body sides, and a cross bar R at their upper ends forminga handle proper.

It is frequently necessary to vary the distance between the rake teethand the ground, and for this purpose I have provided an adjustingmechanism adapted to be conveniently actuated by the operator in usingthe rake, for shifting the teeth longitudinally of the body for thepurpose set forth, and rovide further means for holding the teet intheir different positions of adjustment. The mechanism employed consistsof a cross bar S fixed to the handle sections, a similarlongitudinally-adjustable bar T mounted in guides U upon the handles forlongitudinal movement, connecting rods V oining the movable bar T andthe adjustable toothcarrying bar G, and a locking mechanism W. Thelatter means consist preferably of a lever pivoted upon the cross bar S,having of engagement with the bar T when desired.

Upon movement of the rake along the ground, the material is collected bythe rake teeth, and the carrier, actuated by the supporting wheels,conveys the material. along the body and deposits it into thereceptacle. The series of teeth are varied in their relation to theground by the shifting of the transverse bars through the agency of theoperating lever, and are held in any desired position in relation to theground by engaging the lever ends in the apertures in the movable bar T.

What I claim. as my invention is;

1. In a hand-rake, the combination with an upwardly-extendingrearwardly-inclined body section, of supporting wheels for said body atthe lower forward end thereof, a supporting frame for and depending fromthe ody, and a transverse roller j ournaled in said frame, rake teethcarried by the body, and a handle section at the rear of said body.

2. In a rake, the combination with an upwardly-extendingrearwardly-inclined body section, of supporting wheels therefor, aseries of rake teeth carried by the body at its lower forward end andadjustable longitudinally of the body, and a handle section for andextending rearwardly from the body.

3. In a rake, the combination with an upwardly-extendingrearwardly-inclined body section, of supporting wheels therefor, aseries of longitudinally adjustable teeth at the lower end of the bodyextending forwardly therefrom in substantially the plane of sai body,means for adjusting the teeth, and a handle section for and extendingrearwardly of the body.

4. In a rake, the combination with an upwardly-extendingrearwardly-inclined body section, and a series of rake teeth along thelower edge of the body extending forwardly therefrom in substantiallythe plane of said body, the teeth ends being return-bent extendingrearwardly at an acute angle to the body in a position to slide upon theground.

5. In a rake, the combination with a body, of a tooth-carrying barhaving a sliding engagement therewith, a handle section for the body, alongitudinally-adjustable member upon the handle section, and anoperative connection between the former and the toothsupporting bar.

6. In a rake, the combination. with a rearwardly-inclined body section,of a toothcarrying section at the lower end and adjustablelongitudinally of the body, and a bridging member carried by one of thesections and acting to bridge the space between said sections.

7. In a rake, the combination. with a body, of an adjustabletooth-carrying bar forming a continuation of the body at its forwardend, and a plate extending over the bar and body and bridging the spacebetween.

8. In a rake, the combination with an upwardly-inclined body section, ofsupporting wheels therefor, a handle section for the body, a transversebar mounted upon the handle section for longitudinal adjustment, atooth-carrying bar similarly mounted upon the body at its lower end,connecting rods joining the bars, and means for retaining the bars intheir various positions of adjustment.

9. In a hand-rake, the combination with an upwardly-extendingrearwardly-inclined body section, of a tooth-carrying bar at the loweredge and in substantially the plane of the body arranged forlongitudinal adjustment, a series of rake teeth upon the bar, and meansfor adjusting said bar.

In testimony whereof I affix my signature in presence of two witnesses.
